Patent NL-8001445-A (NL)
Title: Loudspeaker with independent localisation for specific positions - has diaphragm of capacitive screens linked to filters for directional characteristics
IPC: H04R19/02
Filed: 1980-03-11
Abstract: The effect of indirect sound in the room, such as reflection from the wall is counteracted. The loudspeaker provides independent localisation facilities for the specific position of the listener in the room. The diaphragm consists of a number of elongated capacitive screesn (2-18) linked to a low pass filter unit (19) with a number of low pass filters (20-27). The effective radiating surface is reduced with increasing frequency, making it approx. equal to a selected factor times the frequency corresp. to the wavelength of the signal being radiated. This achieves a directional characteristic related to the azimuthal orientation.

Title: Device for decontaminating drain water and feed water in agriculture and horticulture
IPC: C02F1/68
Filed: 1991-10-28
Abstract: Device for decontaminating drain water and feed water in agriculture and horticulture, based on the known principle of oligodynamics. For this purpose, existing oligodynamic devices are amended in such a manner that the principle can be applied to water with an acidity of lower than 7 in which fertilizers are dissolved, the sterilization automatically being adapted to requirements. The device may moreover add additional oxygen, manganese and iron ions to water and is provided with means for recovering and reusing metal ions which are dissolved in water. Furthermore, the device is able to give out free metal ions with the used feed water, which ions have a long- term sterilizing action in the root area of plants, thus avoiding or limiting the use of herbicides (pesticides).

Abstract: A heald singularizing system includes a selecting member (21) for the healds (LI) fed in the form of a stack (LS). The selecting member (21) separates the front-most heald (LI1) from the stack and makes it available for the drawing-in of the warp threads. The selecting member (21) is formed by a piston which can perform a stroke essentially transversely to the heald stack (LS), during which the heald (LI1) is displaced from the heald stack (LS) into an intermediate position (ZP). Transfer means (24) transfers the respective heald (LI1) from its intermediate position (ZP) to a transport unit (25) for taking it to its drawing-in position. All types of healds can be selected from the heald stack, and neither a special preparation of the healds nor the use of a special type of heald is necessary. The heald separation and the further removal are completely uncoupled, to permit the use of means optimally adapted to the individual functions and also to simplify considerably the rectification of faults.

Abstract: 一种γ－LiAlO 2 /α－Al 2 O 3 复合衬底材料的制备方法，包括如下具体步骤：在铂金坩埚内，放置有带气孔的LiAlO 2 和Li 2 O混合料块；将双面抛光或单面抛光的蓝宝石α－Al 2 O 3 晶片置于或悬于铂金丝上，加上覆盖有LiAlO 2 和Li 2 O混合粉料和热电偶的坩埚盖，坩埚顶部加铂金盖密闭，置于电阻炉中；该电阻炉加热升温至1000～1400℃左右，恒温20～100小时，Li 2 O扩散到α－Al 2 O 3 晶片中，降温后可得到LiAlO 2 /α－Al 2 O 3 复合衬底材料。本发明克服了α－Al 2 O 3 衬底晶格失配度大和难以获得大尺寸高质量LiAlO 2 单晶衬底等问题，可用于生长高质量InN－GaN薄膜外延生长。

Abstract: 本发明提供一种电梯控制装置，当电梯到层开门前，电梯乘载轿厢的一个到层位置处于预定范围的到层高度时，接通并输出锁销拉上指令信号(DLRY)，拉上轿厢门锁定装置(2)的锁销，解除锁定，开始开门操作。当关门时与关门同时，机械地落下锁销实施锁定。因此，除了到层楼层打开电梯门的情形外不使电梯门打开地进行锁定，能够防止发生当电梯升降中和紧急停止时乘客从电梯门跌落的情况。
